ABSTRACT: In this article, we study the 3/2+{3\over 2}^{+} heavy and doubly heavy baryon states \varXi*cc\varXi^{*}_{cc}, \varOmega*cc\varOmega^{*}_{cc}, \varXi*bb\varXi^{*}_{bb}, \varOmega*bb\varOmega^{*}_{bb}, \varSigmac*\varSigma_{c}^{*}, \varXic*\varXi_{c}^{*}, \varOmegac*\varOmega_{c}^{*}, \varSigmab*\varSigma_{b}^{*}, \varXib*\varXi_{b}^{*} and \varOmegab*\varOmega_{b}^{*} by subtracting the contributions from the corresponding 3/2-{3\over 2}^{-} heavy and doubly heavy baryon states with the QCD sum rules, and we make reasonable predictions for their masses.

Article: Analysis of the flavor antitriplet heavy baryon states with QCD sum rules
[Hide abstract]
ABSTRACT: In this article, we study the masses and pole residues of the flavor antitriplet heavy baryon states (, and (, by subtracting the contributions from the corresponding heavy baryon states with the QCD sum rules, and observe that the masses are in good agreement with the experimental data and make reasonable predictions for the unobserved bottom baryon states. Once reasonable values of the pole residues λ Λ and λ Ξ are obtained, we can take them as basic parameters to study the relevant hadronic processes with the QCD sum rules.

• Article: Baryon sum rules and chiral symmetry breaking
[Hide abstract]
ABSTRACT: In an SVZ-type approach sum rules for baryonic currents have been investigated, without radiative QCD corrections but with the inclusion of non-perturbative terms due to the non-vanishing vacuum expectation value of the quark-antiquark condensate. We give upper bounds for baryon masses, which allow a choice of optimal interpolating operators for low-lying baryon states. The results show that the mentioned vacuum expectation value not only sets the scale for parity splitting but also for the masses of the baryons directly. The alternative way of explicit symmetry breaking by quark masses has also been investigated in the same technical framework.
